Abstract


The behavior of intact and immobilized invertase in aqueous and water-organic media has been studied. In a water-organic medium, the transferase properties of the enzyme changed: pH optima of intact and immobilized invertase undergo shifts of 0.5 units: the temperature optimum decreases (50 degrees C and 25 degrees C in aqueous and water-organic media, respectively). The extent of conversion of isoamyl alcohol in water-organic medium shows a dependence on several factors (the enzyme and substrate concentrations; amount of the organic phase; and duration of the enzyme incubation with the substrate). Optimum parameters of isoamyl alcohol conversion were used for transforming fusel alcohols into alkyl fructosides. The results of this applied research have important practical implications (conversion of fusel oils of alcoholic beverages).
